In case you're worried, this mod does not affect the "Turn Signal" or "Hazard" lights - Everything will function as expected, and you'll simply have a way to disable/enable DRL on demand, with an On/Off switch.

It was actually simpler than I expected... As shown below, all you have to do is interrupt the DRL signal, which is on the "Light-Green & Red" wire of the DRL harness (harness with 2 plugs on it - Part #82241-04030), which is connected to the DRL-capable relay (Part #81980-35020). Refer to the DIY mentioned above for suplementary installation instructions.
